When this fish is a juvenile it can be kept in brackish conditions with other larger brackish fish such as the Mono. As it matures it needs to be in full Marine, and can be kept with large semi-aggressive Marine fish, but bear in mind that this fish can swallow up 67% its body length! These fish prefer to be in groups of 4 or more.

Please note this fish is often sold as freshwater, which is of course wrong.

A very active scavenger. Can be aggressive towards those smaller than itself and smaller fish will indeed become prey. Should be indifferent towards larger fish as long as they keep out of this fish's way.

Elongated silver iridescent body, the belly is white. The fins are tipped with white and black. Large protruding eyes. Three sets of barbels. They also have venomous dorsal spines so need extra care when being handled.
